Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of rolling mills, in particular to heat treatment equipment for producing working rolls of a multi-roller rolling mill. Background Art

[0002] A rolling mill refers to the equipment that enables metal rolling. It broadly refers to the equipment that completes the entire process of rolling production, including primary equipment, auxiliary equipment, lifting and transportation equipment, and ancillary equipment. However, the term "rolling mill" generally refers only to the primary equipment. Rolling mills are said to have existed in Europe as early as the 14th century, but the only documented design for one is a sketch by the Italian Leonardo da Vinci in 1480. In 1553, the Frenchman Brulier rolled gold and silver plates for use in coinage. Subsequently, rolling mills appeared in Spain, Belgium, and the United Kingdom. Existing heat treatment equipment for the production of multi-roll mill work rolls has difficulty reciprocating the heat during the heat treatment process, which can easily lead to incomplete heat treatment. Furthermore, the rolls need to be more securely fixed during the heat treatment process. To address this issue, a heat treatment system for the production of multi-roll mill work rolls is proposed.

[0003] Application number 202221832807.8 discloses a quenching and tempering heat treatment device for the production and processing of alloy steel castings, which relates to the field of casting technology. To solve the problem that alloy steel castings in the prior art need to be heat treated during production and processing, they are generally heat treated by boiler heating and water tank cooling. This requires the alloy steel castings to be removed from the boiler, but the removal work is very inconvenient. A first roller is provided inside the boiler, and the first roller is rotatably connected to the boiler by support legs. A material tray is provided above the first roller, and a handle is fixedly installed above the material tray. A slide is slidably connected to the bottom of the transverse movement device, and a first hydraulic jack is fixedly installed below the slide. The lifting end of the first hydraulic jack is fixedly installed with a connecting plate. A second hydraulic jack is installed below one end of the connecting plate, and the second hydraulic jack is fixedly connected to the connecting plate by bolts. A second clamp is installed at the lifting end of the second hydraulic jack.

[0004] However, there are shortcomings in this device. A first hydraulic jack is fixedly installed under the slide, and a connecting plate is fixedly installed at the jacking end of the first hydraulic jack. A second hydraulic jack is installed under one end of the connecting plate, and the second hydraulic jack is fixedly connected to the connecting plate by bolts. A second clamp is installed at the jacking end of the second hydraulic jack to facilitate the removal of the cast steel parts. However, it is not suitable for heat treatment of the working rolls of multi-roll mills. The heat treatment equipment for the production of working rolls of multi-roll mills is difficult to reciprocately heat the roll body during the heat treatment process of the roll body, which easily leads to incomplete heat treatment, and during the heat treatment process, it is necessary to strengthen the fixing effect of the roll body.
