Product model: ND-DQ9
Product features: At present, most of the five elements in steel can be detected in China are split testing, and the product types of integrated testing are less. Taking the currently popular ND-DQ9 five elements analyzer as an example, the instrument can freely enter or delete the standard sample point when establishing the standard sample curve, repeatedly perform regression processing, and determine the curve choice according to the correlation coefficient. The construction of standard curve completely realizes digitalization and formulation, and gets rid of the traditional backward method of manual curve construction. It can easily call and modify the curve, and carry out man-machine dialogue, so that the scope of use of the instrument has been greatly expanded.

ND-DQ9 type five elements analyzer uses
The five elements analyzer is used to test the content of manganese, phosphorus, silicon, carbon and sulfur in steel. Manganese, phosphorus, silicon, carbon and sulfur in steel are the most important and basic elements, so we are used to calling them the five elements of steel. According to the current standard GB/T5613-1995 cast steel grade expression method and GB/T5612-1985 cast iron grade expression method, it is explained that the five elements are to distinguish the grade and quality of ordinary steel, and its content directly affects the mechanical properties of steel. Steel and casting enterprises regard the inspection of the five elements of the product as one of the most important inspection.
Development basis
Manganese (according to GB/T 223.63-1988 standard) was oxidized by silver salt - ammonium persulfate spectrophotometry.
Phosphorus element (according to GB/T 223.61-1988 standard) using sodium fluoride - stannous chloride molybdenum blue degree method
Silicon element (according to GB/T 223.5-1997 standard) using ferrous reduction - silicon molybdenum blue degree method
Carbon (according to GB/T 223.69-1997 standard) adopts the gas capacity method
Sulfur element (according to GB/T 223.68-1997 standard) adopts iodine measurement
