Description
Technical field:
The present invention relates to a kind of magnesium alloy continuous casting method and apparatus, especially belong to a kind of twin-roll continuous casting method and apparatus that all thickness magnesium alloy plate is produced that is used for.
Background technology:
Magnesium alloy plate is to adopt extruding and rolling method manufacturing substantially at present.Extruding and rolling are made magnesium alloy plate production procedure complexity, and productivity ratio is low, and the production cost height can not satisfy the needs that magnesium industry develops.The continuous casting technology of Development and Production rate height, magnesium alloy plate that production cost is low has very significant meaning.The method of domestic and international also continuous casting of no use is produced the technology of magnesium alloy plate at present, and this type of technology is the forward position research and development problem of present world magnesium industry circle.
The scheme of double-roll type continuous casting was proposed by Bei Ximai in 1846, nineteen fifty-one U.S. Hunter-Douglas company develop double-roll type continuous casting milling train.Many aluminium manufacturers and aluminum profile extrusion factory once used bottom pouring type twin-roll continuous casting milling train to produce aluminium plate.Because of the operation of horizontal and tilting twin-roll continuous casting milling train, debugging, maintenance have tangible advantage without bottom pouring type twin-roll continuous casting milling train.After generation nineteen sixty, twin-roll continuous casting milling train ejection speed is slow in order to overcome, the roll deformation problem, adopts the method that increases roller diameter, and roller diameter has reached about 1 meter at present.
The twin-roll continuous casting unit is made up of three parts: smelting system, continuous casting system and finishing system.Smelting system comprises: smelting furnace, leave standstill stove (liquid storage, insulation, degasification, temperature control); Continuous casting system comprises: conticaster, preceding case, feed mouth, strand guide roller; The finishing system comprises: hauling machine, cutter, tension flattening machine, coiling machine.Wherein the effect of preceding case is to control the pressure that is entered the molten metal of casting roller by stem bar, guarantees that promptly metal bath surface will have stable height and temperature.The feed mouth is directly molten metal to be distributed the critical component that enters the casting roll gap.Structural requirement to the feed mouth: molten metal by the time streamline rationally and do not have the dead angle, molten metal is uniformly distributed in roll gap, molten metal is the temperature uniformity when roll gap.The quality of feed mouth assembling directly influences feed mouth service life and slab quality.
Various countries' twin-roll continuous casting milling train is mainly used to produce aluminium and aluminum alloy plate materials blank.Many countries have produced 0.6～2 meter wide, the fine aluminium and the aluminium alloy made-up belt of 6～10 millimeters thick with twin-roll continuous casting.This blank can be used as the blank of rolling aluminium foil, also can do the blank of aluminum products.The zine plate, printing that other material also has dry cell is with plate etc.
Still the useless both at home and abroad twin-roll continuous casting unit of producing in magnesium alloy plate.This is because compare with other material, and the greatest difficulty of the twin-roll continuous casting of magnesium alloy plate is very easily oxidation of magnesium alloy, burning even blast; In addition, the thermal capacitance and the latent heat of magnesium alloy deformation performance less, magnesium alloy is relatively poor, so the design of the twin-roll continuous casting of magnesium alloy must meet the characteristics of magnesium alloy, especially prevents the oxidation, burning of liquid magnesium alloy, will prevent that magnesium alloy from blasting especially.Thereby existing aluminium alloy twin-roll continuous casting unit is not suitable for the production of magnesium alloy.Basic problem is that liquid magnesium alloy is extremely active, easy oxidizing fire, easy with nearly all violent chemical reaction of refractory material generation that is used for aluminium alloy, the melting of aluminium alloy and mode of movement can not be used for the melting and the conveying of magnesium alloy, casting roller lubricant is not suitable for magnesium alloy yet, especially very harsh to the requirement of feed mouth material during roll-casting of magnesium alloy, certain high temperature mechanical performance, good heat insulating and not reacting with liquid magnesium alloy again again should be arranged, also should have the ability that prevents the liquid magnesium alloy burning, existing material can't meet the demands.The thermal capacitance of magnesium alloy and latent heat are also little than aluminium alloy, and the control of continuous casting process process is difficulty relatively.
Summary of the invention:
The object of the present invention is to provide a kind of twin-roll continuous casting method and apparatus that is applicable to that magnesium alloy plate is produced.To be magnesium alloy be transported to after the smelting furnace fusing that holding furnace is incubated leaves standstill in the technological process of described twin-roll continuous casting method; liquid magnesium alloy is transported to the preceding case stem bar that adopts integrated design then; keep liquid magnesium alloy constant temperature and keep the permanent height of magnesium alloy liquid level and the anti-oxidation burning of gas shield is arranged in case stem bar before this, last liquid magnesium alloy enters the casting and rolling machine casting and the anti-oxidation burning of gas shield is arranged from case stem bar before this.And magnesium alloy is transported to after melting furnace fusing and also can removes by filter impurity when holding furnace is incubated.The twin-roll continuous casting equipment that magnesium alloy plate is produced, mainly induction system and preceding case, stem bar, casting and rolling machine and the cutter by Mg alloy smelting furnace, holding furnace and liquid magnesium alloy constitutes, and it is characterized in that preceding case, stem bar adopt integrated design to form incorporate preceding case stem bar; Be provided with heater that keeps liquid magnesium alloy constant temperature and the height controller that keeps the permanent height of magnesium alloy liquid level in the case stem bar before this.Smelting furnace, holding furnace are adopted in the acquisition of liquid magnesium alloy, under gas shiled, carry out melting and insulation when satisfying twin-roll continuous casting high-quality alloy liquid supply requirement in a large number and continuously.Adopting siphon pipe or pump for the conveying of the safety and steady that guarantees liquid magnesium alloy carries, be mingled with and the twin-roll continuous casting requirement liquid magnesium alloy supply of high degree of purification continuously based on easy formation of magnesium alloy, adopt the method for foam ceramic filter, because easy oxidation of liquid magnesium alloy and burning, the thermal capacitance and the latent heat of magnesium alloy are little, therefore before case and feed mouth adopt integrated design so that simple in structure, area of dissipation is little, the liquid magnesium alloy flow process is short in case oxidation and constricted flow problem.In order to prevent the heat-insulating property of preceding case of the same case of liquid magnesium alloy and feed mouth generation chemical reaction and raising and feed mouth, the feed mouth adopts extraordinary composite manufacturing.Temperature for the online adjusting liquid magnesium alloy of energy, the preceding case feed mouth of integrated design be equipped with in the preceding case stem bar called of the present invention in thermoelectric heater or outside heater, interior thermoelectric heater is by the heating action of thermoelectric heater in thermocouple in the liquid magnesium alloy and the controller control.The strip casting process liquid magnesium alloy is with needing lubricant control liquid magnesium alloy with heat exchange and diffusion and chemical reaction etc. between the roll between the roll, lubricant adopts and with liquid magnesium alloy chemical reaction does not take place, polluted product not, have simultaneously put out the liquid magnesium alloy burning capacity, with roll in conjunction with good suspension.
