AI Technical Summary

Technical Problem

The use of bottom-blown permeable bricks at the bottom of existing steel and iron ladles leads to high consumption of refractory materials, frequent maintenance, and difficulty in accurately determining the safe thickness, which affects the efficiency and safety of the steelmaking process.

Method used

A partition wall structure is set at the bottom of the bag to divide it into multiple independent areas. The breathable bricks and steel outlet are set in different areas. The partition wall is made of high-strength material, and the surface of the protruding permanent layer is coated with anti-slag coating to facilitate inspection and maintenance.

Benefits of technology

It reduces the consumption and maintenance time of refractory materials, improves the integrity of the furnace lining structure and the turnover speed of steel ladles and iron ladles, enhances safety, and reduces baking costs and accident risks.

Abstract

This invention discloses a ladle bottom with a partition wall structure for steel or iron ladles, comprising a permanent layer and a working layer sequentially cast into the bottom. A partition wall is provided between the permanent and working layers, dividing the bottom into multiple independent areas. The lower part of the partition wall is embedded in the permanent layer, and the upper part is embedded in the working layer. Bottom-blown permeable bricks are also provided on the bottom, placed within the corresponding independent areas. This invention reduces destructive operations on the entire ladle bottom, reduces refractory material consumption and operation time, and also helps improve the integrity of the furnace lining structure. It can reduce the amount of furnace bottom castable, increase construction speed, improve the safety of steel or iron ladle operation, and reduce the occurrence of accidents.
