A sub-gun probe temperature measuring bracket and its processing method

Abstract

The invention discloses a processing method for a temperature-measuring bracket of a sub-gun probe, which comprises the steps of: setting an injection mold; fixing a compensation wire; clamping a mold, punching and welding a stand; injection molding a bracket; and cooling and demoulding. This processing method can fix the positive electrode compensation wire and the negative electrode compensation wire while injecting the plastic bracket, and at the same time use the stamping force when the injection mold is closed to form a soldering platform. The height of the welding platform is at the same horizontal position, and the compensation wire fixing structure of the injection mold can ensure that the two compensation wires remain fixed during the stamping and injection molding process. The processing method of this scheme eliminates the assembly process of the plastic bracket and the compensation wire in the past, ensures that the height of the soldering platform of the compensation wire is consistent, ensures the stability and accuracy of the temperature measurement of the sub-gun probe temperature measurement bracket, and simplifies the processing technology and improves the efficiency. Processing efficiency. The invention also discloses a sub-gun probe temperature measuring bracket processed by the above-mentioned processing method.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a sub-lance probe temperature measuring bracket and a processing method thereof. Background technique [0002] Sub-lance technology is the most important means of converter automation steelmaking. Through the sub-gun measurement system, the static and dynamic control of the converter can be realized, which has completely changed the traditional steelmaking mode and the history of relying on experience in steelmaking. During converter blowing, sublance probes are used to measure some parameters related to molten steel quality. The sub-lance probes used in the process provide important data support for the dynamic model correction of the sub-lance technology, and the sub-lance probes used at the end point provide the basis for the furnace chief to quickly tap steel. [0003] At present, there are two types of sub-gun probes for converters: temperature measurement, sampling, c...

AI Technical Summary

Problems solved by technology

The existing processing technology has the following defects: 1. The height of the positive and negative electrode soldering stations cannot be guaranteed to be consistent, which affects the accuracy of temperature measurement; 2. The part where the positive and negative electrode compensation wires cooperate with the plastic bracket is in the shape of a cylinder, which is easy to rotate in the bracket , resulting in desoldering of solder joints; 3. The processing steps are complicated and the processing efficiency is low
