受河北省科委委托,由河北省冶金局主持的轧钢加热炉用耐火可塑料大型予制块技术鉴定会,于八二年十二月九至十日在马家沟耐火材料厂召开。来自全国有关科研院所高等院校及工厂企业等16个单位的25名代表参加了会议。研制耐火可塑料大型予制块是河北省科委八○年初下达给马家沟耐火材料厂的试制项目。第一批样品于八○年八月开始在天津轧钢一厂热带和开坯车间二座连续式加热上进行工业性试用。两年多的生产实践证明,耐火可塑料大型予制块,具有耐高温,耐高
Commissioned by the Hebei Provincial Science and Technology Commission, hosted by the Hebei Provincial Metallurgical Bureau of the rolling furnace with refractory plastic large pre-block technology appraisal meeting, December 12, December 10 at Majiagou refractory plant was held. Twenty-five representatives from 16 institutes, including institutions of higher learning and factories and factories in relevant research institutes across the country, attended the conference. The development of refractory plastic large pre-block Hebei Provincial Science and Technology Commission issued early 80 to Majiagou refractory plant trial project. The first batch of samples began industrial trial in August of 1980 in the continuous heating of two blocks of the tropical and bloom shop of the first rolling mill in Tianjin. More than two years of production practice has proved that fire-resistant plastic large pre-block, with high temperature, high resistance
