Description

Take the sample spoon of converter splash slag

technical field

The utility model belongs to the field of sampling tools, in particular to a spoon for taking a sample of slag splashed by a converter.

Background technique

There are many types of raw materials used in converter steelmaking. When the composition of molten iron fluctuates greatly and the amount of raw materials containing FeO is large, the converter is prone to splashing. Especially in recent years, in order to reduce the production cost and alleviate the tension of iron ore, Shuigang has used some domestic vanadium-titanium magnetite in the blast furnace batching. Because the proportion of vanadium-titanium ore added is not high, the vanadium content in the molten iron has not reached the minimum vanadium extraction. Requirements, vanadium extraction treatment cannot be carried out, so the molten iron entering the converter contains a certain proportion of vanadium, titanium, chromium and other elements. Such elements will have adverse effects on converter smelting, resulting in slag foaming, difficult separation of steel slag, reduced metallurgical effect, and increased loss of metallic iron. If splashing occurs again, the splashed slag will take away a large amount of metal.

In view of the severe foaming during vanadium-titanium hot metal smelting and a large amount of metals in the slag, methods such as adding a slag inhibitor can be used to reduce the foaming of the slag, thereby reducing the metal content in the slag, but the price of the slag inhibitor is relatively expensive. If each furnace of steel Adding it will increase the production cost. In the past, because there was no special tool for taking out the splashed slag, the metal content in the slag could only be judged by human eyes, and the accuracy was poor, which was not conducive to controlling the production cost.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a simple in structure, fast and safe, convenient and practical, and save production cost to take the sample spoon of converter splash slag.

The purpose of this utility model and its main technical problems are solved by adopting the following technical solutions:

The utility model is a sample spoon for taking converter splash slag, including a handle, a long rod and a sample spoon, one end of the long rod is provided with a handle, and the other end is provided with a sample spoon, wherein: the sample spoon is a hollow body, and its lower part is a cylinder shape, the upper part is trumpet shape.

The slag-like spoon from the converter splashed above is taken, wherein: the handle is 10-15 cm long.

The slag sample spoon from the converter splashed above is taken, wherein: the long rod is 2-3m long.

Take the sample spoon of the converter splashed slag, wherein: the long rod and the sample spoon are connected by welding.

The above-mentioned spoon for slag splashed by a converter is taken, wherein: the long rod and the handle are connected by welding.

Compared with the prior art, the utility model has obvious beneficial effects. It can be seen from the above technical solutions that the sample spoon is a hollow body, the lower part of which is cylindrical, and the upper part is in the shape of a trumpet. The upper part is in the shape of a trumpet to increase the contact area of the splashed slag, which is convenient to pick up the splashed slag, while the lower part is a hollow cylinder, so that the slag and metal entering the sample spoon will not run out due to the falling impact; The slag-splashing tool shaft is 2-3m long. This enables the sampling personnel to take samples outside a safe distance, which can avoid scalding the sampling personnel from splashing slag. The above design makes it unnecessary to take down the furnace when sampling, and does not need to cooperate with other people. It is easy to use, fast in sampling, and does not affect the operation of the converter. Repeated use, the service life is more than 5 years. The long rod and the sample spoon, and the long rod and the handle are connected by welding, and the welding method is simple and firm, safe and reliable, and low in cost. In a word, the utility model has the characteristics of simple structure, fast safety, convenience and practicality.

The specific implementation manner of the present utility model is provided in detail by following embodiment and accompanying drawing thereof.

Detailed ways

Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the furnace-sprayed slag-like spoon proposed according to the utility model will be described in detail below.

Referring to Fig. 1, the tool for taking the sample spoon of converter splashed slag of the present invention includes a handle, a long rod and a sample spoon, one end of the long rod is provided with a handle, and the other end is provided with a sample spoon, wherein: the sample spoon is a hollow body , the lower part is cylindrical, and the upper part is horn-shaped; the handle 1 is 10-15cm long; the long rod 2 is 2-3m long; the long rod 2 is welded to the sample spoon 3; Handle 1 is welded connection.

During use, the raw materials of the converter change greatly, especially when smelting molten iron containing vanadium and titanium, if the slag foams, steel slag is difficult to separate, and is easy to splash during this period, you can manually take the splashed slag when the converter is splashing For the sample spoon, put the horn of the spoon against the splashed slag, keep the horn surface stable, and the spoon can be filled with slag in 1-2 seconds. After taking the sample, leave the sampling point and return to the safe area. After the slag in the sample spoon is solidified, gently tap the bell mouth towards the ground, and the slag sample can be separated from the sample spoon. Since the specific gravity of metal iron is larger than that of slag, the metal substance will settle. In the lower part, the upper part is slag, and the ratio of metal in the slag can be manually observed to judge whether there is no separation of steel slag.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any modifications made to the above embodiments according to the technical essence of the present utility model do not deviate from the content of the technical solution of the present utility model. Any simple modifications, equivalent changes and modifications still belong to the scope of the technical solution of the present utility model.
