Abstract
The present invention relates to novel solid steel ingot mould paint which comprises the main components of micro powder graphite with high dispersed performance, solid water glass, cellulose, aluminum silicate, etc. The present invention is used for protecting steel moulds during casting moulds and making steel in metallurgy steel making industry. Meanwhile, the paint decreases steel ingot surface defects caused by the irregular inner surface of moulds and poor casting conditions, and has the advantages of no operation environment pollution and notable economic technical devices. The present invention is ideal steel ingot mould paint in smelting industry at present.
Description
The invention belongs to metallurgical steel industry ingot mould special solid powder.
At present, all use liquid coating at metallurgical steel industry mould coating material both at home and abroad,, reduced the harm of pernicious gas human body though operating environment is improved significantly than brushing tarvia, the technological process of operation is simplified to some extent, and the quality of surface of steel ingot increases.But because of contain the moisture of 30-80% in coating, bring very big difficulty for the remote transportation of product, especially transportation in winter and storage are more inconvenient.Liquid coating is emitted a certain amount of harmful gas in use in addition, pollutes working environment.
The objective of the invention is to use the defective that exists in transportation, the storage, designed a kind of novel preparation mould coating material solid powder at stating product.This invention improved the physical and chemical index and the result of use of mould coating material product, the environmental requirement that has especially adapted to the north of china in winter transportation and stored, and the pollution of no operatton environment has guaranteed the physical and mental health of operating worker.

Two, the preparation ingot mould is coated with and uses the solid powder technological process of production:
1, the technological process of production:
As shown in the figure: its technological process of production is: in the process oven dry respectively of suspending agent, binding agent, carrier and diffusant, detection; Broken and detect after prepare burden, lump together stirrings, grindings again with through pulverizing graphite after detecting, pack after detecting.
2, processing parameter: (parameter that in the technological process of production, adopts)
(1) reducing agent (graphite) adopts high pressure draught to pulverize, and flow is 6-12m
3/ minute, pressure is 5-9kg/cm
2
(2) oven dry of material is adopted the far-infrared rays drying case, its bake out temperature:
Suspending agent: 123 ℃-150 ℃;
Binding agent: 120 ℃-200 ℃;
Diffusant: 85 ℃-100 ℃.
(3) batch mixing adopts vertical twin-shaft mixer.
Mixing time is 45-60 minute.
The present invention removes to have the Ingot Surface Quality of improvement, reduces the mould consumption, improves lumber recovery and billet yield, prolongs steel ingot service life, and the no operatton environmental pollution is guaranteed to reduce production costs in addition outside staff's psychosomatic health, effect such as increase economic efficiency.As adopt solid powder to compare with liquid coating, then solid powder is by 1: 5-1: the calculation of price after 9 water distributions, the whole nation are promoted the use of total amount and are about 9.000 tons, can use product producer to obtain about ten thousand yuan of benefit 1.500-1.980.The metallurgical industry system promotes the use of in the whole nation, and its technical economic benefit can reach 2.25 hundred million yuans.
Most preferred embodiment of the present invention (optimum formula):
