Casting construction mold for water-cooled column and water-cooled beam of heating furnace

Abstract

The invention relates to a casting construction mold for water cooling columns and water cooling beams of heating furnaces. The casting construction mold for water cooling columns and water cooling beams of heating furnaces comprises a water cooling column mold, a three-way mold and water cooling beam molds and is characterized in that: the water cooling column mold is mainly composed of a pair of water cooling column half molds which are assembled; the three-way mold is mainly composed of a pair of three-way half molds which are assembled; each water cooling beam mold comprises a U-shaped water cooling beam mold and a plurality of U-shaped wood jigs, and the U-shaped wood jigs are fixedly connected with the outer side of the U-shaped water cooling beam mold along the length direction. The mold can ensure that cast products of water cooling columns and water cooling beams can be accurately positioned, the structure of straight sections is straight, the phenomena of pitted surfaces and anchoring nail exposure do not exist at beam-column joints, water cooling beam slopes can be formed by casting in one step, the casting quality is increased, and potential quality hazards are eliminated.

Description

technical field [0001] The invention relates to a casting construction mould for a heating furnace water-cooled column and a water-cooled beam. Background technique [0002] The water-cooled beam of the heating furnace is divided into a movable beam and a fixed beam, and the steel ingot is transported from the feeding end of the heating furnace to the discharging end in a stepping method. The steel ingot is gradually heated, and impurities such as iron oxide on the surface of the steel ingot fall off and slide down the upper slope of the water-cooled beam. In the past construction of water-cooled beam pouring materials, the upper slope needs to be smeared twice, which is easy to delaminate and fall off after being heated; if it is formed by one-time pouring, the slope cannot be formed, so that the iron oxide cannot slide down, resulting in partial burnout of the steel ingot, which affects the rolling. quality. [0003] There are two types of water-cooled beam and column mo...

AI Technical Summary

Problems solved by technology

The production cost of the steel mold is high (about 100,000 yuan for a set of molds), it is bulky and difficult to operate, and it is easy to rust; the wood mold is easy to operate, but the clamps commonly used in the construction industry take up space, which affects the transportation of materials during construction, and is reinforced with screws , it is necessary to increase the number of wooden squares and increase the construction cost

[0004] There are common problems in the previous steel molds and wooden molds: 1. The bottom of the water-cooled column is easy to deviate; 2. The joints of the tee molds are prone to pockmarks and exposed anchor nails; 3. The slope on the upper surface of the water-cooled beam, due to the ceramic The fiber mat has a certain degree of elasticity, and the castable will crack before it reaches the strength

4. The junction between the slope of the water-cooled beam and the straight section is not straight; 5. The thickness of the insulation layer on both sides of the water-cooled beam is uneven
