Description

Technical Field

[0001] This application relates to the technical field of the manufacturing method of the key component - the crystallizer copper tube in continuous casting equipment in the metallurgical industry, and particularly relates to a plum blossom-shaped crystallizer copper tube manufacturing device and its manufacturing method. Background Art

[0002] In modern steel production, the continuous casting machine is one of the most important devices for realizing high-efficiency and high-quality billet production. Among them, the crystallizer, as the core component of the continuous casting machine, its performance directly affects the quality and output of the final product. Traditional crystallizer copper tubes mostly have a circular cross-section. Although the processing is relatively simple, there are problems such as uneven cooling and heat stress concentration in actual use, resulting in poor surface quality of the cast billet. In recent years, with the development of metallurgical technology, some crystallizer copper tubes with new cross-sectional shapes have been gradually studied and applied, such as elliptical and flat shapes. These designs aim to improve the cooling effect and the quality of the cast billet.

[0003] Currently, the commonly used manufacturing methods of crystallizer copper tubes mainly include the following several types: 1. Preparation of traditional circular cross-section copper tubes: Method 1: Adopt the spinning forming method, and gradually form the copper tube material by rotating the die. This method has a lower cost, but the accuracy is not high, and it is easy to produce dimensional deviations.

[0004] Method 2: Cold drawing forming method, and perform multiple stretches on the pre-formed copper tube to make it reach the required size and shape. This method can ensure higher dimensional accuracy, but has high requirements for equipment and low efficiency.

[0005] 2. Preparation of non-circular cross-section copper tubes: Method 3: Adopt the precision casting method. First, prepare a wax mold with a specific cross-sectional shape, and then form the copper tube by pouring molten metal. This method can achieve complex cross-sectional shapes, but the process is complex, the cost is high, and it is easy to produce pores and cracks.

[0006] Method 4: Laser cutting method, and precisely cut the required cross-sectional shape on the pre-prepared copper tube using a high-energy laser beam. This method has high precision and strong adaptability, but the equipment investment is large and the maintenance cost is high. In the related art, the existing manufacturing methods of crystallizer copper tubes generally have the following problems: 1. High cost: Especially in the preparation of non-circular cross-section copper tubes, the costs of methods such as precision casting and laser cutting are much higher than traditional methods.

[0007] 2. Low production efficiency: Whether it is cold drawing forming or precision casting, it takes a long time to complete the entire process and cannot meet the needs of large-scale production.

[0008] 3. Difficult to control dimensional accuracy: Especially in the application of large continuous casting machines, tiny dimensional errors will affect the working performance of the mold, and further affect the quality of the cast billet.

[0009] 4. Poor quality stability: Due to the complex production process, products of different batches may have large differences, which brings difficulties to subsequent production and maintenance. Summary of the Invention
