Description

Technical Field

[0001] The invention belongs to the technical field of metal smelting, and relates to a disposable slag breaking probe for temperature measurement and sampling and a temperature measurement and sampling slag breaking method. Background Art

[0002] There are a large number of processes in the metallurgical production process that require temperature and composition detection of molten high-temperature metals. When measuring temperature or sampling, the probe needs to penetrate the slag layer on the metal surface and insert it into the molten metal to a certain depth. Because the slag layer is hard and forms a hard shell in most cases, it is generally necessary to break the slag before detection.

[0003] In the prior art, slag is broken using a slag breaking gun, which is a special non-standard equipment, but has a high manufacturing cost, and metal and slag will stick to the gun during use, making it difficult and time-consuming to clean, resulting in a longer operation cycle. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a disposable slag breaking probe for temperature measurement and sampling and a slag breaking method for temperature measurement and sampling, so as to solve the problems of high cost and long time of existing temperature measurement and sampling slag breaking.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A disposable slag-breaking probe for temperature measurement and sampling comprises a tube body and a conical cone head arranged at the front end of the tube body, the tube body comprises a first tube section and a second tube section arranged in a front-to-rear manner, and the length L1 of the first tube section is greater than the thickness of the slag layer; the first tube section is a hard tube, comprising a paper tube and a refractory layer arranged on the outer surface of the paper tube; the second tube section is a soft tube made of the same material as the paper tube, and is an integral structure with the paper tube; the inner diameter and length of the tube body match the connector rod of the temperature measurement and sampling so that the rear end of the tube body can be plugged into the connector rod of the temperature measurement and sampling.

[0007] Optionally, the paper tube is a waterproof paper tube.

[0008] Optionally, the material of the paper tube is the same as that of the temperature measuring sampling probe.

[0009] Optionally, the material of the cone head is the same as that of the refractory layer.

[0010] A temperature measurement sampling slag breaking method comprises the following steps: firstly, a disposable slag breaking probe is connected to the front end of a temperature measurement sampling connector rod; secondly, the temperature measurement sampling connector rod is inserted into molten metal to a certain depth to break the slag; then, the connector rod is pulled out; and then, the disposable slag breaking probe is manually pulled out or separated from the temperature measurement sampling connector rod by automatic scraping.

[0011] The beneficial effects of the present invention are that the slag breaking probe is as easy to connect as the temperature measuring sampling probe. After the slag breaking operation is completed, the slag breaking probe can be removed manually or separated from the temperature measuring sampling connector rod by automatic scraping, and can be discarded after use. No other equipment is required for temperature measuring sampling, which solves the problems of high cost of existing temperature measuring sampling and long operating cycle due to cleaning difficulties. In addition, the slag breaking probe is made of paper tube and refractory material, which is low-cost, economical and applicable, and has broad market prospects.

[0012] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS
