Abstract
Heat preserving agent for liquid steel, this agent is by flyash, light building material and binding agent are made, flyash accounts for more than 60% of gross weight, light building material accounts for 10-30%, binding agent accounts for below 10%, above-mentioned material is weighed up in proportion, earlier powder binder and an amount of water with spare, other material is poured into mixer, again the mixed liquor of powder binder and water is also poured into mixer and stir, put into extruder then and extrude, the irregular graininess heat preserving agent of extruding is baked to water content below 10%, it is placed on around the steel ingot in molten steel surface or the casting process, makes the cooling of molten steel or steel ingot slowly, have the advantage that high insulating effect and free from dust are flown upward.
Description
Be used for insulation when the present invention is molten steel casting, make the molten steel cools of steel ladle slowly reach the heat preserving agent that makes steel ingot cool off slow usefulness in the casting process.
Be used at present insulation during molten steel casting, molten steel cools in the steel ladle is reached slowly make steel ingot cool off slowly in the casting process that method is after molten steel flows into steel ladle, in molten steel surface and casting process, put carbonization rice husk on the steel ingot, carbonization rice husk floats on molten steel surface, or carbonization rice husk is placed on around the steel ingot, reach insulation, make in the steel ladle molten steel cools slowly and make steel ingot cool off purpose slowly.The weak point of this method is that heat insulation effect is poor, and dust flies upward in putting carbonization rice husk and entire work process, makes the casting ecological deterioration, is harmful to the casting workers'health.
With the weak point of carbonization rice husk insulation, provide a kind of high insulating effect, the heat preserving agent for liquid steel that free from dust is flown upward when the objective of the invention is to overcome present molten steel casting and continuous casting.
The objective of the invention is to be achieved through the following technical solutions, the flyash more than 60% that accounts for the material gross weight, 10～30% light building material, powder binder below 10%, weigh up in proportion, earlier powder binder and an amount of water with spare, then above-mentioned all the other materials are poured into mixer, again the mixed liquor of powder binder and water is also poured in the mixer and stirred, make it fully mixed, mixed material is placed in the extruder extrudes, when the heat preserving agent for liquid steel of extruding ruptures voluntarily during to certain-length or cuts off, the heat preserving agent for liquid steel of the humidity that the extruder extrusion is fallen down toasts, drying by the fire water content can pack below 10%, the back is placed on it above molten steel molten steel covered and can plays insulation effect in molten steel flows into steel ladle, in casting process heat preserving agent is placed on around the steel ingot, makes the steel ingot cooling slowly.
Protect the insulation of Gentle carbonization rice husk with this heat preserving agent and compare, have easy to use, good heat insulating, advantage such as free from dust is flown upward during use, and environment is clean.This
An embodiment that has advantage especially of the present invention is a flyash 75～80% in the gross weight of filling a prescription, light building material accounts for 12～20%, powder binder accounts for 2～5%, after above-mentioned material weighed up in proportion, earlier powder binder and an amount of water with spare, then above-mentioned all the other materials are poured into mixer, again the mixed liquor of powder binder and water also being poured into mixer stirs, make it fully mixed, mixed material is placed in the extruder extrudes, the heat preserving agent for liquid steel of the humidity that the extruder extrusion is fallen down dries by the fire water content and is getting final product packed for standby use below 10% through overbaking.
