Introduction and Features of Furnace Roll

1.Introduction

Furnace rolls are manufactured from small caliber Φ60mm-Φ1600mm, a variety of national standard materials of heat-resistant alloy steel empty-belt furnace bottom rolls. The furnace temperature varies from 850 ℃ to 1200 ℃, and the materials used are also different. Suitable for annealing of ordinary carbon pipes, oil well pipes, stainless steel pipes, etc. Especially for the production of large-diameter furnace bottom rolls for continuous annealing production lines that require higher reliability.

Furnace roll is very important in heat treatment technology, because it can affect the final quality of various workpieces during the annealing process, so people have very high requirements for the furnace bottom roll, not only can withstand high temperatures, but also have Very good anti-oxidation ability, the importance of the arm shaft sleeve in the driving, so as to ensure the quality of the processed objects to the greatest extent. Therefore, it is also important to have a good usage habit in ordinary use, and also to maintain it regularly, so that the time of the furnace bottom roller can be extended.

Furnace roll is an important equipment in the metallurgical industry. It is an indispensable processing equipment. It is mainly used in annealing furnaces. Its production requirements are high and it needs high safety and reliability, high temperature resistance, etc. Affects operating efficiency.

The quality of the furnace roller affects the quality of the product surface. If traditional graphite carbon sleeves and ceramic-coated rollers are used, phenomena such as roller surface oxidation, furnace roller nodules, and loose pineapples will be prone to affect normal production activities. Quartz ceramic hollow rollers have the characteristics of high strength, high temperature resistance, small thermal expansion, good chemical stability, stable high temperature performance, no deformation, smooth and delicate surface, good abrasion resistance, etc., which can avoid replacement operations, improve efficiency and improve the surface quality. In addition, it has a long service life and is not easy to wear for a long time. Zh

The development of China’s metallurgical industry also has many years of history. The demand for furnace bottom rollers has also continued to increase. The furnace roller industry has also made great progress. There has been a great improvement in performance and safe use. Everyone must be sure when choosing Pay attention to choosing the right equipment.Furnace Roll2.Performance

The quality of the bottom roll of the silicon steel continuous annealing furnace is one of the main factors affecting the operation rate and the surface quality of the product. Traditional graphite carbon sleeves and ceramic coated rolls are prone to surface oxidation, furnace nodule, loosening and flaking Phenomenon that affects normal production.

Quartz ceramic hollow roller has the characteristics of high strength, high temperature resistance, small thermal expansion, good chemical stability, stable high temperature performance, no deformation, smooth and delicate surface, and good abrasion resistance. It is the traditional graphite carbon sleeve and ceramic coated roller. Ideal alternative product. It can effectively solve the problems of oxidation and nodulation, avoid frequent replacement operations, improve operation efficiency, and significantly improve the surface quality of steel strips.

Long-term use is not easy to wear, which is 3-5 times the life of the carbon sleeve, and the used old roller can be used repeatedly after reprocessing, which greatly prolongs the service life and reduces the production cost.

The use temperature is up to 1100 ℃, especially suitable for continuous annealing furnace of high grade silicon steel.

Using the company’s original fine quartz ceramic manufacturing technology that has won the third prize of national scientific and technological progress, the development and development of quartz ceramic furnace bottom rolls has a history of nearly ten years, and its performance has reached the level of similar foreign products. It is used by a well-known silicon steel production enterprise and has achieved the same effect as imported products used in the same furnace.

It can provide the design and use unit with reasonable structure of the bottom roller design process parameters, ensure the quality of the bottom roller assembly and the use effect.

3.Features

Oven hearth rollers are made of various national standard heat-resistant alloy steel empty-belt hearth rollers from small caliber Φ60mm-Φ1600mm. The furnace temperature varies from 850 ℃ to 1200 ℃, and the materials used are also different. Suitable for annealing of ordinary carbon pipes, oil well pipes, stainless steel pipes, etc. In particular, large-diameter furnace bottom rolls for continuous annealing production lines requiring higher reliability are manufactured.
