Abstract

The utility model discloses a tungsten carbide roller which comprises a roller shaft. A tungsten carbide roller ring is sleeved on the roller shaft, the tungsten carbide roller ring is in interference fit with the roller shaft, ferrules are sleeved at two ends of the tungsten carbide roller ring, and the ferrules are in interference fit with the roller shaft. The tungsten carbide roller has the advantages of being good in abrasion performance, high in rolling tonnage and the like, and brings abundant benefits and rewards to a manufacturing shop. After experimental testing, the tungsten carbide roller improves the following production benefits that the tungsten carbide is used, a production process is further stabilized, and simultaneously, negative deviation control stability is brought. According to an existing production level, after the tungsten carbide is used, deformed steel bar minus deviation can be improved by 0.2%, therefore, the tonnage steel benefit is 0.2%*3500=7yuan/ton, according to the phenomenon that 12-22deformed steel bar is produced 100,000 tons per year to conduct calculation, benefits can be improved by 7*10=700,000 yuan, and due to the facts that surfaces of steels rolled by tungsten carbide roller are smooth and attractive, the steels are sold well and price of steel per ton can be improved by 20 yuan.

Description

A kind of tungsten carbide roll

Technical field

The utility model belongs to roll, relates in particular to the roll that a kind of collar is used tungsten carbide material.

Background technology

Roll commonly used is composite roll, and the cladding material of composite roll has chilled cast iron, unbounded chilled cast iron, spheroidal graphite cast-iron, rich chromium cast iron, steel alloy, half steel, high chrome, high-speed steel, carbide alloy etc.; The core common used material is casting pig, spheroidal graphite cast-iron, cast steel, forged steel.Shortcomings such as it wears no resistance, rolling tonnage is low, the production cost height.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency a kind of tungsten carbide roll is provided.

For achieving the above object, the utility model is by the following technical solutions:

A kind of tungsten carbide roll comprises roll mandrel, is with carbon tungsten roller ring at roll mandrel, and carbon tungsten roller ring and roll mandrel are interference fit, is arranged with lasso at the carbon tungsten roller ring two ends, and lasso and roll mandrel are interference fit.

Above-mentioned tungsten carbide roll, the magnitude of interference between described roll mandrel and the carbon tungsten roller ring is 0.07mm-0.1mm.

Adopt technique scheme, the utility model has following advantage: good, the rolling tonnage advantages of higher of wearability, brought abundant benefit and repayment to workshop.

Through experiment, the productivity effect of using the utility model to improve is as follows:

⑴, use tungsten carbide have further been stablized production process, have brought minus deviation control stable simultaneously.According to the existing level of production, use tungsten carbide rear thread steel minus deviation can improve 0.2%, therefore ton steel benefit is produced 100000 per year according to ∮ 12-22 screw-thread steels and is calculated at 0.2% * 3500=7 unit/ton, can increase the benefit: ten thousand yuan of 7 * 10=70;

, because carbon tungsten roller ring rolled steel performance smooth surface is good-looking, therefore appearance is better, can improve 20 yuan of ton steel, produce 200000 tons of calculating per year according to Ф 16,18,20,22 circles and ∮ 16,18,20,22 spiral shell specifications, can increase the benefit: ten thousand yuan of 20 * 20=400.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

A kind of tungsten carbide roll as shown in Figure 1, comprise roll mandrel 1, be with carbon tungsten roller ring 3 at roll mandrel, carbon tungsten roller ring and roll mandrel are interference fit, be arranged with lasso 2 at the carbon tungsten roller ring two ends, lasso 2 is interference fit with roll mandrel, and back-up ring can be fixed on collars on the roll, prevent the collars dislocation, avoid influencing pass processing and rolling.The magnitude of interference between described roll mandrel and the carbon tungsten roller ring is 0.07mm-0.1mm.

Claims

1. tungsten carbide roll, comprise roll mandrel (1), it is characterized in that: be with carbon tungsten roller ring (3) at roll mandrel, carbon tungsten roller ring and roll mandrel are interference fit, be arranged with lasso (2) at the carbon tungsten roller ring two ends, lasso (2) is interference fit with roll mandrel.

2. according to the described tungsten carbide roll of claim 1, it is characterized in that: the magnitude of interference between described roll mandrel and the carbon tungsten roller ring is 0.07mm-0.1mm.
