In early April, the brown corundum and sub white corundum markets in Henan Province remained stable. The mainstream tax content of brown corundum pouring furnace sand in Henan region is 4350-4450 yuan/ton, and the mainstream tax content quotation of fixed furnace sand is 4300-4400 yuan/ton. The mainstream tax inclusive quotation for Yabai corundum section sand is 5200-5300 yuan/ton.

The current production enthusiasm of enterprises producing brown corundum in Henan region is not high, and the sales proportion of refractory materials in the market is gradually decreasing. Some enterprises have stated that in order to maintain their survival, considering the current demand and profit situation of the refractory material market, they have gradually reduced the processing ratio of segment sand and fine powder, and used more block materials to process into grain size sand to supply abrasive and other grinding wheel production enterprises. However, this state has been maintained in many parts of the refractory material market.

Individual Yabai corundum production enterprises have slightly increased their prices by 100 yuan/ton. It is reported that the supply of high-quality bauxite raw materials for Yabai corundum has been affected by some enterprises, and the shortage of raw materials has led to a slight price increase. On the other hand, the current market demand for Yabai corundum is limited, and it is mostly produced on demand.
