Abstract
A slagging-off device belongs to the ironmaking and steelmaking industry. At present, most steel works adopt traveling cranes for draining slag, which causes serious molten steel loss during the operation, slag cannot be drained completely, and 50-80 percent even less slag with inaccurate ingredients is drained, steel ladles require to be rotated back and forth, the safety is poor, the efficiency in vacuum melting is influenced, and huge loss is caused. According to the invention, the slagging-off operation is performed manually or mechanically, the consumed molten steel during the draining is reduced through adopting the special slagging-off device equipped before the steel ladle, more than 80 percent of slag is drained, the cost is reduced, and the safety in slag draining is improved in a manner that the steel ladle is not rotated and is equipped with a firming frame.
Description
Technical field
This facility belongs to the smelting iron and steel industry, is exclusively used in steel mill.
Background technology
Advancing vacuum metling at molten steel all needs as last slag strained and removes, most at present steel mills all are to adopt driving to strain slag, the loss molten steel is serious when straining slag, slag is strained unclean, strain the quantity of slag generally between 50% to 80%, need to come the back rotation ladle down to poor stability simultaneously, the efficient that influences vacuum metling also causes tremendous loss to cost.
Summary of the invention
Adopt artificial or machinery is skimmed, be equipped with the molten steel amount of losing when special use draws the slag facility to strain slag with reduction before ladle, and the slag 80% or more strained remove, the while is not rotated ladle and the security when being equipped with firm frame and straining slag with raising to ladle.
Claims (2)
1. the supporting plate in the facility of skimming before the vacuum.
2. skim platform and the power in the facility of skimming before the vacuum.
