Embodiment 1

[0016] The binder for adjusting the plasticity of the clay is composed of the following components in parts by weight: tar: 85 parts; ethanol: 2 parts; ethylene glycol: 10 parts; dichloroethyl ether: 3 parts.

[0017] The above-mentioned tar by weight and the other three solvents are respectively added and mixed evenly during the stirring process, and packaged for storage. Add the solid raw material of the gun clay and mix and roll; the measured value of the plasticity index Maxia of the gun clay is 0.9Mpa; after standing for 7 days, the Maxia value is 1.3Mpa.

Embodiment 2

[0019] The binder for adjusting the plasticity of the gun clay is composed of the following components in parts by weight: tar: 70 parts; ethanol: 5 parts; ethylene glycol: 5 parts; dichloroethyl ether: 10 parts; toluene: 5 parts; o-xylene: 5 servings.

[0020] The tar in the above ratio and other five different solvents are respectively added and mixed evenly during the stirring process, and packaged for storage. Add the solid raw material of the gun clay and mix and roll; the measured value of the plasticity index of the gun clay is 0.7MPa; after standing for 7 days, the Maxilla value is 1.1Mpa.

Embodiment 3

[0022] The composition range of the binder for adjusting the plasticity of the clay is: tar: 90 parts; ethylene glycol: 3 parts; dichloroethyl ether: 1 part; toluene: 3 parts; p-xylene: 3 parts.

[0023] The above-mentioned tar and four other different solvents are added and mixed evenly during the stirring process, and packaged for storage. Add the solid raw materials of the gun clay and mix and roll; the measured value of the plasticity index of the gun clay is 0.95MPa; after being placed for 7 days, the Maxia value is 1.3Mpa.

Abstract

The invention discloses a binding agent for regulating the stemming plasticity. The binding agent consists of the following components in parts by weight: 70 to 90 parts of tar, 0 to 5 parts of ethanol, 1 to 10 parts of ethylene glycol, 1 to 10 parts of dichloroether, 0 to 10 parts of toluene, and 0 to 10 parts of dimethylbenzene. According to the binding agent, the tar can be in a good dissolving state, the normal temperature plasticity of the stemming can be effectively improved, and the stemming regulation can be facilitated; the boiling points of ethylene glycol and dimethylbenzene in the added solvent components can be relatively higher, stable at normal temperature, and cannot be easily volatilized, so that the plasticity of stemming can be constantly improved; and the product is low in cost, and has a good effect.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a binder for adjusting the plasticity of gun clay. Background technique [0002] Most of the blast furnace clay binders used in large blast furnaces are tar, but the blast clay produced with tar alone tends to harden and difficult to adjust at room temperature, and has poor plasticity, making it difficult to perform mud drilling operations, which affects the workability of the blast clay at the tap hole. Combining resins such as phenolic resin with tar or anthracene oil can improve the plasticity of gun clay, but resins are generally not easy to mix with tar, and the price of resins is still very high. Contents of the invention [0003] The purpose of the present invention is to provide a binder for adjusting the plasticity of the blasting clay. The application of the binder helps to overcome the poor plasticity of the blasting clay at normal temperatur...
