Molten steel oven
钢水烘炉
To use molten steel oven, it is necessary to bake the knotted lining first, and add a part of waste steel to the bottom of the furnace. The steel should be dense and rust-free solid material to prevent the bottom of the furnace from being washed by molten steel.
用钢水烘炉需要先将打结好的炉衬进行烘烤，在炉底加入一部分废钢材，钢材应选择密实无锈的实心块料，防止炉底被钢水冲毁。
After charging, the furnace lining is baked with low power, about ten hours, the furnace lining is fully preheated, and the furnace mouth is also baked by wood or gas.
加料后用小功率通电对炉衬进行烘烤，大致十小时左右，对炉衬进行充分预热，同时对炉口也采用木材或煤气等方式进行烘烤。
After baking, power off, inject molten steel, pay attention to the falling point and flow rate of molten steel, do not directly impact the furnace wall, after injecting molten steel, stand for 15-30 minutes, and then power up to heat up, keep the heating rate at 100℃ / h;
烘烤结束后断电，注入已经熔化好的钢水，注意钢水落点和流速，不能用钢水直接冲击炉壁，注入钢水后静置15-30分钟，再通电升温，保持升温速率为 100℃ / h；
At this time, the metal temperature in the furnace is measured every ten minutes. When the metal temperature reaches 1680~1700℃, the heat preservation begins. The steel is kept for more than 2 hours, and the oven is completed.
此时每隔十分钟测一次炉内金属温度，当金属温度到达1680~1700℃ 时开始保温，保温2小时以上出钢，烘炉完成。
