The application discloses a kind of medium wideband centrifugal composite steel supporting roller's quenching and tempering heat treatment method, belongs to supporting roller heat treatment technical field, solve the technical problem that after using existing supporting roller quenching and tempering heat treatment method, roll neck cracking or roll body hardness is unqualified.It is included in the quenching and tempering heat treatment method of the application: step 1, supporting roller is heated and kept warm as a whole;Step 2, after keeping warm, supporting roller is taken out of furnace, and is hoisted and transported to spray quenching bed;Step 3, carry out regional quenching treatment on spray quenching bed, reciprocating rotating supporting roller during regional quenching treatment process;Step 4, supporting roller after quenching is loaded into furnace and is tempered;Step 5, after tempering, the hardness of supporting roller is detected.The application is different for roll body roll neck material, and cooling is carried out by different cooling methods, and the production of high-quality centrifugal composite steel supporting roller product is realized.

A method for verifying and controlling the consistency of environmental protection levels during the production process includes: Step 1: An environmental engineer determines the environmental protection level of materials and customer projects and records it in the MES system, generating a QR code with embedded data including the environmental protection level of the materials, and attaching a production process flow sheet containing the QR code to the materials; Step 2: During the material cutting and feeding process, a scanning device scans the QR code attached to the materials. The MES system determines whether the environmental protection level of the materials embedded in the QR code is consistent with the environmental protection level of the customer projects recorded in the MES system. If they are consistent, the MES system allows the material cutting operation to begin; Step 3: During the finished product shipping process, a scanning device scans the QR code affixed to the finished products. The MES system determines whether the environmental protection level embedded in the QR code is consistent with the environmental protection level of the customer projects recorded in the MES system. If they are consistent, the MES system allows the finished product shipping operation to begin. This invention improves production quality stability, increases production efficiency, reduces manpower input, and saves time.

This application relates to the field of steering ratio fluctuation calculation and evaluation technology, specifically, to a method for calculating and evaluating automotive steering ratio fluctuation, comprising the following: constructing an ADAMS improved steering system model, which includes upper fork modeling, lower fork modeling, and column adjustment modeling; specifically, a dual revolute joint modeling method is adopted, namely a first revolute joint and a second revolute joint; obtaining a front suspension model and simulation boundary conditions; assembling the front suspension model and the steering system model; and simulating the process to obtain the instantaneous steering ratio fluctuation curve; performing a multi-dimensional evaluation based on the instantaneous steering ratio fluctuation curve; and determining whether to adjust the phase angle based on the multi-dimensional evaluation results to simulate the actual structure of the steering intermediate shaft universal joint, thereby avoiding discrepancies between simulation results and reality.
