Metallurgical slag basin model-free casting method

Abstract

The invention provides a metallurgical slag basin model-free casting method. The metallurgical slag basin model-free casting method includes the following steps: four corner cores of a slag basin are manufactured with a corner core box, the outer contour of the four corner ends of the casting slag basin are obtained, and a casting outer contour sand mold of the casting slag basin is formed; skin repairing is carried out, wherein a multi-layer plate or molding sand is adopted to filling and assembling of a casting cavity part, and the slag basin sand mold profile is formed; sand discharging is carried out to form a sand core box; and core discharging and box closing are carried out. Compared with an original method that casting is carried out through a manufacturing mold, the method has the beneficial effects that the length, the width and the wall thickness of the slag basin can be adjusted, so that the slag basin in any size can be manufactured, multiple molds are replaced, repeated utilization can be carried out, and the mold cost is greatly reduced; and meanwhile, the problem of uneven wall thickness of a casting is solved, and the wall thickness accuracy of the slag basin casting 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
