Description

A kind of preparation process of molding composite heating plate
Technical field
The invention belongs to technical field of refractory materials, more particularly to a kind of preparation process of molding composite heating plate.
Background technology
When Baogang Stocks Trading Co.'s steel mill molding 85.9 1 phase of producing line goes into operation, molding cast is thrown by the phase after being cast in ingot mould Enter exothermic mixture (making fever material, additional oxidant, flux, agent of catching fire etc. with metallic aluminium powder) and carry out extension headers setting time, improves Ingot head shrinkage cavity, but exothermic mixture input box-hat portion generates prodigious dust and smog, it is strong to the body and mind of execute-in-place worker Health impacts, after had developed one kind at 91 years or so and can use HRV92-1 type heating boards in molded cap, product warp It crosses after the static ingot filling pipe end use of cast steel subsidiary factory, heating board extremely can be good to the ingot quality produced, especially to ring Border, environmental protection, safety play sure effect, use till today always.But it is higher and higher with the ingot quality requirement of molding production, It is found by practical investigation, since heating board is to be previously positioned at ingot head opening, molding is poured after steel starts, and molten steel enters steel ingot In mould, be placed on the heating board of ingot mould cap mouth in mould liquid steel level rising occur as soon as too early ignition, expansion, fever etc. Undesirable element affects the effect of heating board normal use, and heating board advanced combustion product is fallen into ingot mould, is produced to steel quality Raw pollution, and due to advanced combustion heat release, molten steel, which rises to after cap mouth, to be really needed adstante febre and causes calorific value insufficient, to Influence cap mouth feeding.
