Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] The invention provides a finishing method for anti-knock damage of steel, and the finishing method comprises the following steps:

[0028] Step 1, hoisting the off-line steel to obtain a steel bundle. In the specific implementation, the steel must be hoisted after the steel is off the assembly line. The specific method is to bundle the steel into steel bundles with iron wires. When hoisting two or more bundles of steel together, the head of the bundled iron wire will not scratch the surface of the steel.

[0029] In step 2, the steel bundle in step 1 is carried out in the finishing process, and the steel bundle is hoisted by a sling. In step 2, when the steel is hoisted, a sling is used to pass under each bundle...

Abstract

The invention provides a finishing method for preventing knocking and bumping steel; the finishing method comprises the following steps of: step 1, lifting the offline steel to obtain a steel bundle;step 2, hoisting the steel bundle in step 1 by a sling during the finishing process; step 3: finishing the steel, specifically comprising straightening, chamfering and automatic flaw detection; duringthe process of straightening, chamfering and automatic flaw detection, adding soft contact material to a steel-based material contacting with the steel, and obtaining the steel meeting the requirements; and step 4, storing the steel meeting the requirements in step 3 on a steel shelf, and adding soft contact to the steel shelf during the storage process. The finishing method provided by the invention not only makes the steel for producing mechanical parts more safe and stable during the process of off-line, transportation, finishing and storage, reduces the defect rate of the product, effectively eliminates the steel knocking and bumping, and makes the quality of the steel more reliable and achieves good economic benefits.

Description

technical field [0001] The invention belongs to the field of finishing of steel production in the metallurgical industry, and in particular relates to a finishing method for preventing knocking and damage of steel. Background technique [0002] At present, more and more steel mills are gradually devoting themselves to the development of steel for automobiles, especially for passenger vehicles, in order to break through the situation that commercial vehicles are the main steel for automobiles. Passenger car customers are increasing year by year for the certification of steel mills. The CVT gearbox pulley project of automobile companies is an important project for the modernization of automobile factories. Automobile companies seek steel mills as partners for development. The company pointed out that there are many bumps on the surface and the depth is different, and there are great quality hidden dangers, which must be rectified. Most of the bumps on site are horizontal and ...
