Description

Automatic production line and process for laminar flow roller production

Technical field

The invention relates to the technical field of production equipment for mechanical processing and surface technology, in particular to the manufacture of laminar flow rollers in a hot-rolled laminar flow cooling system.

Background technique

Laminar flow rolls are located between finishing rolling and coiling in the hot rolling mill for conveying and laminar cooling of the finished strip. During the working process, the laminar flow roller must not only bear the impact and wear of the hot slab, but also withstand the alternating load (cold and hot fatigue) and local pressing load and contact sliding load under the action of cooling water spray.

The conventional preparation process of laminar flow rollers is turning before sandblasting-sandblasting-welding-remelting-finishing after welding. Among them, turning before spray welding is mainly to process the laminar flow roller of the blank to the basic size; blasting is to use the impact of high-speed sand flow to clean and roughen the surface of the laminar flow roller, so that the mechanical properties of the workpiece surface are improved, so the workpiece is improved Fatigue resistance increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating; spray welding is the reheating of the preheated self-dissolving alloy powder coating. The particles are melted, the slag is floated up to the surface of the coating, the generated boride and silicide are dispersed in the coating, so that the particles and the surface of the substrate are well combined, and the final deposit is a dense metal crystalline structure and forms about 0.05～ with the substrate The 0.1mm metallurgical bonding layer has good impact resistance, wear resistance, corrosion resistance, and a mirror appearance; the remelting and refining process refers to the process of metal purification and purification, including the adsorption and dissolution of inclusions in the laminar flow roller.

Based on the complex working environment and high performance requirements of the laminar flow roller, the R&D personnel improved the laminar flow roller preparation process, so that the performance of the laminar flow roller was improved. For example, patent application 201310738506.8 discloses a spray welding coating process for hot-rolled laminar cooling rolls, which includes the following steps: 1) roll blanking and pre-spraying processing; 2) pre-heat treatment of the workpiece; 3) spraying Welding coating: adjust the speed of the roller to 15-20 rpm, turn on the spray gun after adjusting the position of the spray gun, adjust the amount of powder and flame, and at the same time advance the roller at a uniform speed, the speed is 280mm/min, so as to ensure the hardness of the spray gun Carbide is uniformly sprayed on the outer circumference of the roller; 4) The sprayed roller rotates at a temperature of 370°C to remelt the cemented carbide layer on it. After the cemented carbide coating is melted, it is placed in air cooling. That is, a roller with a cemented carbide coating is formed. Cooling rollers spray-welded by this process and tooling have the functions of anti-wear, thermal barrier, anti-oxidation, anti-corrosion, anti-nodulation, anti-adhesion, etc., and have a very long service life beyond the market application roller table.
