Novel prescription of CSP diversion agent and preparation method thereof

Abstract

The invention relates to a guide agent and relative preparation, used in CSP smelt factory, wherein it uses chromic sand, quartz sand, magnesium sand, feldspar sand, and graphite, to be screened, mixed and dried. Compared with present guide agent, it has better sinter degree, stable thickness, and better high-temperature resistance, etc. And the test proves that its steel pack self-open rate can reach 98-100%.

Description

technical field [0001] The invention belongs to the field of metallurgical auxiliary materials, and relates to a drainage agent for steelmaking and continuous casting ladles, in particular to a CSP drainage agent and a preparation method thereof. Background technique [0002] CSP steelmaking and continuous casting production line is the introduction of advanced continuous casting and rolling new technology, which needs to be filled with drainage agent at the ladle nozzle. The drainage agent used in the existing steel mills is made of quartz sand, aluminum sand and graphite as raw materials, which are mixed and stirred. Due to the simple raw material structure and backward preparation process, this drainage agent has poor fluidity, large particle size difference, and contains 1.2% water. When used in CSP ladle, it takes a long refining time and low self-opening rate, within 60-80%. , It often requires manual drainage, which affects the continuous operation of CSP continuous ...

Problems solved by technology

Due to the simple raw material structure and backward preparation process, this drainage agent has poor fluidity, large particle size difference, and contains 1.2% water. When used in CSP ladle, it takes a long refining time and low self-opening rate, within 60-80%. , it often requires manual drainage, which affects the continuous operation of CSP continuous casting and rolling, and in severe cases, the continuous casting and rolling operation will be interrupted
