A slag tank whose trunnion can be tilted outward and its manufacturing method

Abstract

The invention provides a slag ladle with a trunnion capable of tilting outward and moving. The slag ladle comprises a slag ladle main body, two groups of trunnion assemblies which are respectively arranged on two sides of the slag ladle main body as well as pin shafts, wherein each group of trunnion assembly comprises a connecting seat, and a trunnion arranged in the connecting seat; the pin shafts are arranged in the connecting seats in a penetrating manner; the slag ladle main body is correspondingly and fixedly provided with pin shaft seats at the pin shafts; and each connecting seat is hinged to the corresponding pin shaft seat through the corresponding pin shaft. In the application, the trunnion assemblies are integrally hinged to the pin shaft seats through the pin shafts, so the trunnion assemblies can integrally rotate around the pin shafts, and integrally tilt outward and move in the direction away from the slag ladle main body, and further a diversion device is conveniently added on the slag ladle; and the operation of arranging a gap in the slag ladle main body for avoiding the interference between the trunnion assemblies and the slag ladle main body is avoided, and further the integrity of the slag ladle main body is ensured, and structural strength of the slag ladle main body is ensured.

Description

technical field [0001] The invention relates to the technical field of metal smelting equipment, in particular to a slag tank whose trunnions can be tilted outward and a manufacturing method thereof. Background technique [0002] The slag tank is an important equipment for steelmaking in the metallurgical industry, and it is a container used to hold high-temperature slag produced in the process of iron and steel smelting. At present, there are two types of slag tanks: casting slag tanks and welded slag tanks. Casting slag tanks inevitably produce waste slag, dust, exhaust gas, etc. during the production process, which pollutes the environment; welding slag tanks can solve these problems. However, the welding slag tank technology has not been born for a long time, and the variety is not rich enough, so the welding slag tank cannot well meet the various needs of users. For example: Some users need to install a diversion device at the mouth of the slag tank, but the trunnion u...

Problems solved by technology

At present, there are two types of slag tanks: casting slag tanks and welded slag tanks. Casting slag tanks inevitably produce waste slag, dust, exhaust gas, etc. during the production process, which pollutes the environment; welding slag tanks can solve these problems

However, the welding slag tank technology has not been born for a long time, and the variety is not rich enough, so the welding slag tank cannot well meet the various needs of users

For example: Some users need to install a diversion device at the mouth of the slag tank, but the trunnion used to match the driving in the welding slag tank is fixed, such as a welding slag disclosed in the Chinese utility model patent with application number 201621464522.8 At this time, the trunnions fixed together with the slag tank affect the installation of the flow guide device, which cannot meet the needs of installing a flow guide device on the upper part of the slag tank
