Description

technical field [0001] The invention belongs to the field of glass smelting, and more specifically, the invention relates to a hot drilling method on a pool furnace refractory material operating at a high temperature and a hot drilling device for realizing the method. Background technique [0002] In the field of glass smelting and manufacturing, the operating status of the high-temperature pool furnace is the decisive factor for stable production. Therefore, how to ensure the controlled operation of the pool furnace and how to implement the mature process system is one of the most concerned issues for pool furnace workers. The operating state of some functional mechanical devices and electrical components on the pool furnace directly determines the stability of the operating state of the pool furnace. Usually, after a pool furnace has been running for a certain period of time, some functional mechanical devices on the pool furnace are damaged (such as the bubbler on the gl...

Problems solved by technology

[0003] However, it is difficult and risky to drill holes on hot refractory materials. There are four main technical difficulties: First, the site conditions are harsh. Usually, the ambient temperature in the working area is generally above 50°C, and the surface temperature of the refractory materials in the construction site is generally low. It must be above 200°C. Under such conditions, it is very demanding to keep the workers in the best mental state, and to make the drilling operation accurate and perfect, and improving the working environment will inevitably affect the stability of the pool furnace process.

The second is that the drilling operation of hot refractory materials is strict. Since the pool furnace carries high-temperature molten liquid, when the hole diameter is large, it is easy to cause leakage of molten glass, and the leaked molten liquid can easily flow into the refractory material and form a negative impact on the refractory material. Corrosion, which will cause safety hazards of the pool furnace and even shorten the service life of the pool furnace; moreover, when the drilling is inclined, it will bring difficulties to the installation of electrical and mechanical components, and affect the process

The third is that the construction conditions are harsh. Due to the high hardness and high temperature of the refractory material (the internal temperature of the refractory material is as high as 1300°C), it is difficult for ordinary drilling tools to achieve this operation; the fourth is that the force acting on the refractory material during the drilling process must be Appropriate, because the stress and strength of refractory materials will change greatly under high temperature conditions. Improper application of force will easily damage the refractory material; Drilling again, and then it is easy to cause stagnation in the pool furnace glass, thereby disturbing the process

Therefore, it is considered to be a major technical problem in this industry to carry out hot drilling construction on the high-temperature refractory materials of the pool furnace. Due to the normal production and the harsh conditions of the construction site, it is difficult to make the drilling work accurate and perfect.
