Abstract
The utility model discloses an exothermic and insulating riser sleeve for forging. The upper and the lower parts of the exothermic and insulating riser sleeve are made of different materials. The upper part of the riser sleeve is an exothermic and insulating material layer, and the lower part is a insulating material layer. The exothermic and insulating riser sleeve of the utility mode can reduce such deficiencies as oxidization of the surface of the casting at the root of the riser, sand burning, coarse microstructure and honeycomb shrinkage porosity produced in use of other exothermic and insulating riser sleeves, and reduce hot spots at the root of the riser.
Description
Technical field
The utility model relates to utensil used when casting, and specifically, is a kind of Foundry Production heat preservation riser buss.
Background technology
At present, in steel-casting and the production of magnesium iron spare, as adopt common insulated feeder to carry out feeding, often required feeder modulus is bigger, and consumption metal liquid measure is big and feeding efficiency is low, and the feeding effect is bad.Therefore generally do not re-use this common riser buss in some steel-casting foundries, especially the steel alloy production, and adopt special-purpose heat preservation rising head to solve foundry goods shrinkage cavity shrinkage porosity problem more.
The general preparation method of heat preservation rising head makes slip together with mixings such as exothermic material, insulation material, aggregate, binding agents, and the mode of compression moulding or employing vacuum suction filter prepares bright, dark heat preservation riser buss.The main feature of this method is with heating material and insulation material and other raw material batch mixing stirring back compression moulding, although this production technology operation is simple, but, cause the heating effect and the heat insulation effect decline in various degree of rising head because several different qualities materials with function are mixed the preparation riser buss.Its another one major defect is that because this place becomes heat energy-saving position easily, temperature is higher in the place of rising head root near cast(ing) surface, cause selective oxidation serious behind the riser heating material combustion, organize thickly, performance descends, even causes that rising head root casting composition pollutes.And causing scab serious, cleaning makes troubles to rising head.
The utility model content
The utility model has overcome above-mentioned shortcoming, has proposed a kind of heat preservation riser buss.The heat preservation riser buss of this structure can avoid the rising head root that other heat preservation riser buss brings cast(ing) surface oxidation, scab, organize the generation of thick and cellular shrinkage defect, reduce rising head root thermal center.
The technical scheme in the invention for solving the technical problem is:
This heat preservation riser buss is made of riser buss top and riser buss bottom, and improvement of the present utility model is: riser buss top is the heat preservation material layer, and the riser buss bottom is an adiabator layer.
Insulation material is fibrous material, cenosphere, flyash or perlite.
Fibrous material comprises inorganic fibers such as glass fibre, quartz glass fibre, boron fibre, ceramic fibre etc., can also be organic fiber such as paper pulp, wood chip etc.
According to the heat preservation rising head of this programme preparation, the height of rising head root insulation material changes according to different rising head specifications, and in general the riser buss size is big more, and it is highly also big more, is generally 5～50mm.
This heat preservation riser buss top is the heat preservation material layer.Exothermic material is by aluminium powder and/or magnesium powder, and oxygenate is formed.That is, oxygenate must use, and aluminium powder and magnesium powder can use separately, also can aluminium powder and the magnesium powder use jointly.Insulation material also is fibrous material, cenosphere, flyash or perlite with riser buss bottom insulation material.
Above-mentioned oxygenate is a kind of or its combination in brown iron oxide, potassium nitrate and the sodium nitrate.That is, brown iron oxide, potassium nitrate and sodium nitrate can use separately, also can be used in combination in twos, also can the three be used in combination.
The concrete preparation method of this heat preservation riser buss is that two parts about the riser buss branch are separately made, and then the riser buss upper and lower of correspondence is coupled together that wherein connected mode can be a variety of:
Mixing and stirring such as one, insulation material, aggregate, binding agent with certain proportioning, the riser buss bottom of preparing certain size by mould; With the mixing and stirring such as exothermic material, insulation material, aggregate and binding agent of certain proportioning, prepare corresponding riser buss top by mould in addition, the two parts up and down with riser buss couple together then.
Two, in same mould, fill the material of two kinds of difference in functionalitys successively, wherein the under-filled material of riser buss is the insulation material for preparing, aggregate, binding agent etc., exothermic material, insulation material, aggregate and the binding agent etc. that prepare are filled on riser buss top, filling method comprises manual or realizes by equipment, and combining closely through oven dry or riser buss top and the bottom, alternate manner sclerosis back after the demoulding is integral.
Advantage of the present utility model is:
1, riser buss top includes exothermic material, and its heat effect can provide a large amount of heats, guarantees that metal keeps liquid in the riser buss in casting solidification process, realizes effective feeding foundry goods.
2, the riser buss bottom includes insulation material, reduces rising head root molten metal heat and scatters and disappears, and keeps the interior feeding passage of rising head unimpeded.
3, the appearance that exothermic material has been avoided rising head root and foundry goods binding site thermal center is not contained in the riser buss bottom, and this position of bringing is overheated and the thermal response of scaling loss and exothermic mixture and molten metal, effectively reduces the oxidization burning loss phenomenon at this position and organizes thick.
4, reduced the use amount of exothermic mixture in the whole riser buss.

The specific embodiment
As shown in Figure 1, the heat preservation riser buss is made of the riser buss top 2 and the riser buss bottom 1 of dome.Riser buss bottom 1 is an adiabator layer, and present embodiment is a cenosphere, and it highly is 30mm.Riser buss top 2 is heat preservation material layers, and wherein exothermic material is aluminium powder and potassium nitrate, and insulation material is a cenosphere, and the riser buss top and the bottom constitute microbead type heat preservation riser buss.
The heat preservation riser buss is made of riser buss top 2 and riser buss bottom 1.Riser buss bottom 1 is an adiabator layer, and present embodiment is a glass fiber material, and it highly is 5mm.Riser buss top 2 is heat preservation material layers, and material is aluminium powder and iron oxide, and insulation material is a glass fiber material, constitutes fiberglass type composite heating thermal-insulating riser buss.
Embodiment 3
The heat preservation riser buss is made of riser buss top 2 and riser buss bottom 1.Riser buss bottom 1 is an adiabator layer, and present embodiment is a perlite, and it highly is 50mm.Riser buss top 2 is heat preservation material layers, and material is aluminium powder, magnesium powder and iron oxide, potassium nitrate, sodium nitrate, constitutes expanded pearlite lithotype composite heating thermal-insulating riser buss.
