A metallurgical slag basin modelless casting method

Abstract

The invention provides a metallurgical slag basin modelless casting method, which comprises the following steps: using a corner core box to make sand cores at the four corner ends of the slag basin, obtaining the outer contours of the four corner ends of the casting slag basin, and molding the slag basin by means of a scraper, Form the sand mold of the outer contour of the slag basin casting; mend the skin: use multi-layer boards or molding sand to fill and assemble the cavity part of the mold to form the outline of the slag basin sand mold; lower the sand to form a sand core box; lower the core and close the box, compared The original method of casting by making molds. In this method, the length, width and wall thickness of the slag basin can be adjusted arbitrarily, so the slag basin of any size can be made, replacing multiple sets of molds, which can be reused and greatly reduces the At the same time, the problem of uneven wall thickness of castings is avoided, and the wall thickness accuracy of slag basin castings is improved.

Description

technical field [0001] The invention relates to a casting method of a metallurgical slag basin, in particular to a modelless casting method of a slag basin. Background technique [0002] The metallurgical slag basin is mainly used for the storage and transfer of high-temperature slag in the metal smelting process, and is a consumable part in the metal smelting process, such as figure 1 The schematic diagram of the metallurgical slag basin is shown. The metallurgical slag basin is generally made of steel and produced by casting. The traditional casting method is as follows: make a real wooden sample, shape it to form an outer contour; make a wooden inner cavity core box, such as image 3 As shown, sand is filled inside to make a sand core to form the inner cavity of the casting; the core is lowered and the box is closed to complete the casting. This production method consumes a lot of wood to make the model, and the cost of the model is high; the model and the core box are ...

AI Technical Summary

Problems solved by technology

This production method consumes a lot of wood to make the model, and the cost of the model is high; the model and the core box are made separately, and the wall thickness of the slag basin is prone to deviation; the applicability of the mold is small, and once the mold is finalized, only one specification of the slag basin is suitable Production
