Titanium Carbide Guide Roller for Rolling Mill with Excellent Oxidation and Heat Resistance

Product Description

Product Description

Guide roller for rolling mill are a series of rollers that determine the angle and direction of the steel as it is guided through the rolling mill to the mill roll. 

Titanium carbide has proved to be a cost-effective material for the manufacture of guide roller for wire rod mills, having low density, excellent anti-oxidation and wear resistance, coupled with relatively good resistance to thermal shock.

TiC hard-metals have a relatively simple metallographic structure, but for quality control, the grain size and porosity must be controlled. In particular, porosity is the main quality problem since even vacuum sintering cannot completely overcome the problem of oxygen pick-up. However, the hot isostatic pressure sintering process (HIP), introduced in the late 1980s, significantly improved the final quality of TiCs, by solving the porosity problems.

Miller MT10 is specially designed for the demanding operations of today's high speed roll mills, suitable for high speed up to 110m/s, with rotation of approx. 35,000rpm and temperature 800-1000 degree. All Miller MT10 guide roller are produced by SINTER HIP (Hot Isostatic Press) technology to assure the best sintering quality.

 

These alloys are based on steel powder metallurgy with the titanium carbides dispersed in an iron-based matrix and sintered. These materials are magnetic and, in general, can be heat treated to reach hardness levels of around 62-67HRC. In the annealed state, hardness can be 45-50HRC for easy machining by lathe.

Advantages of MT10 guide roller




1. Lighter than Tungsten carbide roller by 55%, Lighter than tool steel than 20%, so the guide roller accelerates from standstill to 35,000 rpm, without damaging the bearing.

2. Very low coefficient of friction and self-lubricating properties, so the working portion of the guide roller is less worn, and the production can be greatly increased

3. The coefficient of thermal expansion is close to that of the bearing steel. When the quenching is hot, the bearing will not get stuck. The thermal expansion coefficients of titanium carbide cemented carbide and tungsten carbide hard alloy are very different from those of steel. Therefore, the steel bonded carbide guide roller is more advantageous for bearing anti-seize ability than the two cemented carbide guide rolls.

4. The micro structure is titanium carbide and high chromium tool steel, which has good thermal fatigue resistance.

5. Anti-oxidation, less magnetic, non-stick steel.

6. Annealing hardness is only HRC45-48, easy to process, after quenching, only a little fine grinding can be processed into finished products, the processing cost is low, so the price is also low. This is also one of the main reasons why titanium carbide guide rolls are superior to tungsten carbide guide rollers.

7. Hardness HRC62-67, good wear resistance. The service life is 8-10 times that of high speed steel.

8. Absolutely dense, the pores are almost zero, so it will not break when used and can be reused.

9. Compared with similar foreign products, the price of Miller MT10 is lower, which greatly saves the production cost of customers.
