Description

Metal smelting filter with multilayer slag stopping function

Technical Field

The utility model belongs to the metal casting field, concretely relates to metal melting filter with multilayer pushing off slag function.

Background

The shunt is needed in the process of pouring molten steel, and the traditional shunt consists of a shunt groove body and a shunt hole. The requirements for the flow divider are different due to different equipment, namely different sizes of the vacuum furnace bodies. The structure design of the shunt needs to meet the following requirements: the temperature loss of the molten steel caused by overlong flow is reduced, the steel liquid storage required by molten steel feeding is reduced, the waste of energy and resources is reduced, and the holding temperature of the molten steel in the steel pipe die is improved to the greatest extent. In order to improve the quality of castings, slag blocking and filtering treatment needs to be carried out on the flow divider. The traditional shunt can not meet the requirement.

SUMMERY OF THE UTILITY MODEL

The utility model provides a metal smelting filter with multilayer pushing off slag function can reduce the impurity stock in the steel ingot, improves the yield of steel ingot and organizational structure's the degree of consistency.

The technical scheme of the utility model as follows:

a metal smelting filter with a multilayer slag stopping function comprises a groove body, two partition plates, four first filter screens and four second filter screens, wherein two first raised lines are arranged on a pair of side walls of the groove body respectively, a horn mouth with a wide upper part and a narrow lower part is formed between the two first raised lines, a first clamping groove is formed in each first raised line, two ends of each partition plate are clamped in the corresponding first clamping groove respectively, and a notch is formed in the middle of the lower end of each partition plate; two convex strips II are respectively arranged on the other pair of side walls of the groove body, and clamping grooves II are formed in the convex strips II; one side of the partition plate is provided with a third convex strip, the third convex strip is respectively positioned at two sides of the opening, and a third clamping groove is formed in the third convex strip; two ends of the first filter screen are respectively clamped in the second clamping groove and the third clamping groove; and filter holes are respectively formed in the four corners of the tank body, and a second filter screen is arranged on each filter hole.

The metal smelting filter with the multilayer slag stopping function is characterized in that a casting cavity is formed between two partition plates, the rest part of the casting cavity is divided into two shunting cavities and four filtering cavities by a first filter screen, and the filtering holes are located in the filtering cavities.

The metal smelting filter with the multilayer slag stopping function has the preferable scheme that the specification of the filter screen is 8-10 PPI.

The preferable scheme of the metal smelting filter with the multilayer slag stopping function is that the second specification of the filter screen is 15-20 PPI.

The utility model has the advantages that:

1. the utility model discloses form the casting cavity of horn mouth form between two baffles, inclusion in the molten steel floats more easily and forms the dross, is blockked by the baffle and prevents that it from getting into the reposition of redundant personnel cavity through the opening of below.

2. The first filter screen can block impurities in the molten steel in the diversion chamber and prevent the impurities from entering the filter chamber, so that the impurity storage amount in the steel ingot is reduced.

3. The second filter screen can block impurities in the molten steel in the filter chamber, so that the impurity storage in the steel ingot is reduced, and the yield of the steel ingot and the uniformity of the organization structure of the steel ingot are improved.
