Recarburizers are mainly used in the foundry industry. As an important additive material in the casting process, high-quality recarburizers can better complete production tasks. When customers purchase recarburizers, how to select high-quality recarburizers becomes an important task. Today, the editor of Furuite graphite will tell you how to choose high-quality recarburizer products:
1. The inspection and acceptance of the recarburizer should be carried out by the professional laboratory personnel in the factory area.
2. The correct method to take the method.
Sample collection method: arrange each bag in a batch of products in a certain order, randomly select one bag from 1 to n bags of products for sampling, and then take a bag every n-1 bag for sampling. The sampling amount is the same, and the collected samples are combined and mixed to serve as the batch of product samples. The number of sampling bags is calculated as follows: x= n/100 (N—the number of bags in each batch). When calculating x with decimals, the decimal part should be rounded off, and when n≤100, samples should be taken from each bag.
3. When sampling, insert the sampler into the bag to extract.
The sample size of each batch shall not be less than 1kg. Use the quartering method to shrink two 500g samples, one for testing and one for reserve. Packaging Specifications Small packaging products are one batch per 100t. If one delivery is less than 100t, it will be counted as one batch; for large packaged products, every 250t will be counted as one batch, and one delivery of less than 250t will be counted as one batch.
Fourth, the recarburizer products should be analyzed and tested for physical and chemical indicators.
For each batch of unqualified recarburizers, if the inspection of the designated recarburizer fails, take double samples to check the unqualified items and then check the recarburizer. If the inspection is still unqualified, this batch of products will be classified as unqualified products. deal with.
