Molten Iron Sampler saves time when collecting samples and guarantees the quality of steel. It is designed to reduce waste, improve economic benefit. The Sampler is divided into single room sampler and double room sampler. Single room sampler is used for scouring and furnace after sampling of molten steel in the tundish ladle, without deoxidization. Double chamber Sampler is used for converter, electric furnace, open hearth to deoxidation of molten steel sampling.
Our sampling success rate is above 98%. The steel sample is full, dense luster and has no pores. Sampler styles can be manufactured according to user's requirements. The main features and application scope for rapid extraction of steel samples for spectral analysis. The utility model has the advantages of simple structure, convenient application and so on.
A. The main technical parameters of hot metal sampler:
1. Sample qualification rate: >90%
2. Steel sample characteristics: full, dense, smooth, no porosity.
B. Method of use:
1. insert the sampler into the special measuring lance;
2. when measuring, the molten steel sampler tilted 60~65 degrees into the steel water, the insertion depth is more than 350mm, the sampling time is 4~6s;
3. sampler is removed from the metal melting furnace, ladle after tapping gently on the ground, the steel sample will fall on the ground.
C. Note:
1. The samplers shall be prevented moisture during storage period;
2. The temperature of molten steel must be no less than1500 DEG C when collecting samples;
3. Avoid strong vibration, to prevent the quartz tube broken;
4. Before using the samplers, they must be put into 60 DEG C oven and baked for 10 hours;
5. The insertion depth and the residence time of molten steel sampler should be strictly executed in accordance with the provisions.
