Abstract
The utility model discloses a water jacket of a square billet withdrawal and straightening machine, which comprises a door-shaped heat shield formed by welding a plurality of flat elliptic hollow steel pipes, wherein the lowest row of the door-shaped heat shield is a solid flat elliptic steel plate, and a water inlet and a water outlet on the door-shaped heat shield are connected with the flat elliptic hollow steel pipes on the upper row of the door-shaped heat shield. The utility model has simple structure, greatly reduced damage and water leakage, reduced failure rate, prolonged service life, lower construction and maintenance cost, safety and reliability.
Description
Technical Field
The utility model belongs to the technical field of continuous casting equipment and instruments, and particularly relates to a water jacket of a square billet withdrawal and straightening machine.
Background
The square billet withdrawal and straightening machine water jacket has the functions of covering a high-temperature casting blank in a machine body area, preventing heat radiation from causing adverse effects on equipment and surrounding environment, and is formed by a front water jacket and a rear water jacket, which are also called a casting blank heat shield, and is generally formed by welding flat elliptic hollow steel pipes, and water is introduced into the water jacket to shield the upper part, the left side and the right side of the high-temperature casting blank in the machine body area, so that the environment is improved, the temperature of the area is close to normal temperature, and the equipment is protected from being damaged by the high-temperature radiation. According to the discovery in the production process, the cooling water jacket damages and leaks and occupies the first failure rate of the withdrawal and straightening machine, and the failure reduces the service life of the withdrawal and straightening machine and other components, and influences the yield of the continuous casting machine and the quality of casting blanks. And more than 90% of water leakage is caused by damage to the inner wall of the steel pipe at the lowest row of the water jacket due to friction and collision of casting blanks after statistics of a maintenance unit of a steel mill.
Therefore, in order to reduce the failure rate of the withdrawal and straightening machine and stabilize the yield and the casting blank quality of the continuous casting machine, improvement of the water jacket of the withdrawal and straightening machine for prolonging the service life is needed.
Disclosure of Invention
The utility model aims to provide the square billet withdrawal and straightening machine water jacket which is simple in structure, low in transformation cost, greatly reduced in damage rate, long in service life, safe and reliable.
The utility model aims at realizing the goal by comprising a door-shaped heat shield formed by welding a plurality of flat elliptic hollow steel pipes, wherein the lowest row of the door-shaped heat shield is a solid flat elliptic steel plate, and a water inlet and a water outlet on the door-shaped heat shield are connected with the flat elliptic hollow steel pipes on the upper row of the door-shaped heat shield.
The utility model has the following technical effects:
according to the utility model, the lowest row of flat oval hollow steel pipes with more friction and collision with casting blanks is changed into a solid steel plate, the water inlet and the water outlet of the original bottom row are upwards moved to the second row of flat oval hollow steel pipes, the friction and collision resistance of the solid steel plate is greatly enhanced, no cold water passes through, the problem that the bottom row is damaged and water leakage is avoided, meanwhile, the friction resistance of the inner side wall of the flat oval hollow steel pipes is increased by the wear-resisting strip, the failure rate is greatly reduced, the water jacket spare part consumption and the maintenance cost are greatly reduced, the service life of the cooling water jacket is prolonged from three months to more than two years, and the service life is greatly prolonged, so that the cooling effect is very little.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic left-hand view of FIG. 1;
in the figure: 1-flat elliptic hollow steel pipe, 2-flat elliptic steel plate, 3-water inlet, 4-water outlet and 5-wear strip.
Detailed Description
The utility model is further described below with reference to the accompanying drawings, without limiting the utility model in any way, and any alterations or substitutions based on the teachings of the utility model are intended to fall within the scope of the utility model.
As shown in figures 1 and 2, the utility model comprises a door-shaped heat shield formed by welding a plurality of flat elliptic hollow steel pipes 1, wherein the lowest row of the door-shaped heat shield is a solid flat elliptic steel plate 2, and a water inlet 3 and a water outlet 4 on the door-shaped heat shield are connected with the flat elliptic hollow steel pipes 1 on the upper row of the door-shaped heat shield.
The outer dimension of the flat elliptic steel plate 2 is the same as that of the flat elliptic hollow steel pipe 1.
Wear strips 5 are arranged on the inner walls of the two sides of the door-shaped heat shield.
The anti-abrasion strip 5 is consistent with the arrangement direction of the flat elliptic hollow steel pipe 1.
The working principle and the working process of the utility model are as follows: the water jacket of the withdrawal and straightening machine shields the upper part, the left side and the right side of a high-temperature casting blank in the machine body region, so that the environment can be improved, the temperature in the region is close to the normal temperature, and the equipment is protected from being damaged by high-temperature radiation. When the casting blank casting machine is used, cooling water enters from the water inlet 3 and flows out from the water outlet 4 to take away heat through the inside of the flat elliptic hollow steel pipe 1, when a high-temperature casting blank passes through the water jacket cover of the casting machine, the casting blank can generate more friction with the flat elliptic steel plate 2 of the bottommost row after transformation, the solid steel plate can effectively avoid the water jacket from being ground through and broken to leak water, the failure rate of the casting machine is reduced, the maintenance working intensity and time are reduced, the service life of the water jacket is greatly prolonged, and the yield and the casting blank quality of the casting machine are also stabilized. The current front and rear water jackets of the steel mill are 28, the number of replacement is reduced from 110 to 10 per year, the unit price of each unit is 5000 yuan, and the annual cost is 5000 multiplied by 100=50 ten thousand yuan.
