Benefits of technology

This patented innovative technique allows for better controllable thermal treatment during manufacturing processes while maintaining consistently good product properties like wear resistance or strength. It achieves this by optimizing specific production parameters and minimizing variations that may lead to poor performance. Additionally, there has been developed an improved continuous cast machine system where rollers used for making metal products have increased durability without requiring frequent maintenance due to their higher temperatures than traditional methods. Overall, these techniques aim to improve the overall efficiency and effectiveness of producing metals efficiently.

Problems solved by technology

This patents discuss different ways to enhance the quality (performance) of ironmaking tools used for excaving buckles from blades made up of multiple layers of stainless steels. These improvements include reducing friction between the tool's surfaces, increasing corrosion resistances, maintaining good thermal conductivity through solid solution diffusion bondings, prevention against oxidative stress crack growth, ensuring proper functioning of the blade under severe environmental stresses like heavy loaders, hydraulic power grinders, cranes, and other equipment. Additionally, these modifications aim towards achieving better wear characteristics without compromising their effectiveness over longer periods of use.

Embodiment 1

[0087] The surface hardness of the hot-rolled materials produced in Examples 1# to 5# is 280 to 330HBW. The hot-rolled materials within the hardness range can not only ensure the mechanical properties, but also solve the difficulty of blanking. Practical issues such as moving steel.

[0088] Processing the above-mentioned rolled material into a short ratio Standard sample blank, after heat treatment, the sample is prepared to measure the longitudinal mechanical properties of steel, heat treatment system: 900±15°C quenching (oil), holding time 50min, 200±10°C tempering (water, air), holding time 4 Hour.

[0089] The mechanical property of table 10 embodiment of the present invention

[0090]

[0091]

[0092]The optimized design of the components ensures better strength and toughness. Since the bucket teeth are in contact with high-hardness objects during the excavation process, the requirements for the impact toughness and surface hardness of the bucket teeth are higher

Abstract

The invention belongs to the technical field of steel for bucket teeth and relates to steel for high-quality bucket teeth for forging and a preparation method thereof. Components of the steel comprise0.27%-0.29% of C, 1.87%-1.97% of Si, 1.15%-1.25% of Mn, smaller than or equal to 0.020% of P, smaller than or equal to 0.010% of S, 2.05%-2.15% of Cr, 0.020%-0.030% of Ti, 0.23%-0.28% of Mo, 0.020%-0.045% of Al and 0.03%-0.05% of V. To solve the problems that discharging is difficult, and hardness distribution and dispersion of the bucket teeth are poor, by optimizing design of the components ofthe steel and production technology parameters, the practical problems that a user cannot discharge hot-rolled materials easily, and cannot carry out sawing, and saw bars are wasted are solved successfully, an obtained product steel has high strength, high hardenability and high purity, the same section hardness of the bucket teeth is more uniform, and the service life of the bucket teeth is prolonged remarkably.
