Selection of steel element analyzers

Casting alloys, copper alloys, aluminum alloys, stainless steels, etc. should pay special attention to the professionalism of the instrument. Generally speaking, professional and sophisticated instrument testing is more accurate and convenient. According to the scale of the company, the demand for equipment is generally divided into three categories: general improvement, economic improvement, and improvement. Ordinary improved type generally can be configured ND-QR9 computer multi-element analysis instrument, laboratory cost can be controlled at 50,000 yuan. As most of the current domestic enterprises in China [1], they must meet the quality control needs, but also to achieve timely and accurate testing, can be configured with a high degree of automation of carbon-sulfur high-speed analyzer and a computer element analyzer, The entire laboratory costs between 15,000 yuan and 25,000 yuan. If non-ferrous metal manufacturers do not need to determine the content of carbon and sulfur, just buy a microcomputer multi-element analyzer and weighing scale, and all chemical glassware. And full set of chemical reagents. For manufacturers with more types of products, it is recommended to select the ND-DB computer multi-element analysis instrument, which has a large enough storage space.

Iron and steel plants mainly use ferrous metals. The purpose of this type of equipment purchase is to ensure that the quality of the company's own products is controlled. Therefore, it is necessary to pay attention to the adaptability of the instrument to the company's products. It is best to print a test report, and the finished product inspection must take into account the authority of the instrument. The single product such as steel, cold-rolled steel and other production units can reduce the professional requirements of the instrument, companies can consider the configuration of a simple ND-80 and ND-QR4 series of carbon and sulfur analyzers, ND-SC elemental analyzer, TG328A type Analyze the balance to build a laboratory, and build a 15 square laboratory with a total price of about 10,000 yuan.

The ND-QR7 liquid crystal automatic carbon-sulfur analyzer and the ND series elemental analyzer can be selected for the pre-stoker test. The laboratory cost is between 22,000 yuan and 25,000 yuan.

The quality, price, and service of the instrument in terms of quality, price, and service of the purchase of the instrument are mainly to consider the service ability of the instrument supplier. Generally speaking, the service quality of the manufacturer is better than that of the merchant. Currently, the high-end product instrument is like a large-scale direct reading spectrum. The price of well-known foreign products is relatively high. The domestic mid-range equipment is more suitable for the needs of SMEs, and the product quality and performance are stable.
