1. preface

Magnesian calcic simple fireproof stuff is a kind of high grade and basic fireproof material, it has a variety of admirable performance characteristics, especially among them free CaO composition, can the metalloid be mingled with such as the 〔 S 〕 in adsorptive molten steel, 〔 P 〕 , Al2O3, have the effect that purifies molten steel. Additional, magnesian calcic simple fireproof stuff is low-cost, pollute without the environment, accordingly, the times favour that accepts people. It is the fireproof data that at present smelt stainless steel and clean steel use ideal. As the constant growth of our country stainless steel and clean steel output, the dosage of magnesian calcic simple fireproof stuff also is increasing ceaselessly. But, the weak point with magnesian calcic simple fireproof the biggest stuff is, carrying, in deposit and using a process, easy imbibe, produce to hydrate, bring about performance characteristics to reduce, serious when still can cause discard as useless. The to hydrate of magnesian calcic simple fireproof stuff affected its development badly, did not get be settlemented very well because of to hydrate problem just about, the magnesian calcic simple fireproof stuff that causes a few new breed cannot get promotion application. Accordingly, to promote the development of magnesian calcic simple fireproof stuff, the gets used to industry of high temperature of steel-making industry etc to develop ceaselessly need that makes its better. Must take effective measures, raise magnesian calcic simple fireproof stuff fight to hydrate function.

2. Raise magnesian calcic simple fireproof stuff to fight the measure of to hydrate function

The essence of to hydrate of magnesian calcic simple fireproof stuff is the free CaO in material and moisture happening reaction, make crystal CaO turns farinose into CaO, accompanying bulk to expand, make the constituent structure of material is destroyed. Accordingly, raise magnesian calcic simple fireproof stuff fight to hydrate function to want to prevent free to CaO and moisture are contacted and produce to hydrate to react namely. Basically take step from the following respects. Should raise magnesian calcic qualitative fireproof raw material above all fight to hydrate function, this is to raise magnesian calcic simple fireproof stuff to fight the measure with to hydrate the basiccest function; The 2nd it is the production in magnesian calcic simple fireproof stuff in the process, avoid raw material and bond belt to enter moisture; The 3rd it is reasonable configuration brick makings; The 4th it is qualitative refractory products undertakes the magnesian calcium that opposite yields sealed pack, those who make is as completely cut off as outside moisture; The production of the 5th production that is will magnesian calcic qualitative fireproof raw material and goods builds serial production line, reduce stock intermediate have enough to meet need, shorten production is periodic.
