BEIJING, July 19 (Reuters) - Chinese steel futures were range-bound on Monday amid concerns of supply crunch as top steel producer China stepped up production curbs, while Beijing vowed to continue monitor commodity market had put a lid on prices.

Capacity utilisation rates of blast furnaces at 163 steel mills across China fell to 76.81%, as of July 16, from 77.61% the week earlier, data from Mysteel consultancy showed. That compared with 85.6% in the same period a year earlier.

"Currently, the biggest variate to affect steel prices is crude steel output control policy ... which is gradually being implemented and widened," analysts with Huatai Futures wrote in a note.

The limit to power consumption due to high temperature in Henan province also led to lower steel production, said Huatai.

The most-traded steel rebar on the Shanghai Futures Exchange , for October delivery, ended up 0.8% to 5,568 yuan ($859.42) per tonne.

Hot-rolled coils, used in the manufacturing sector, inched down 0.1% to 5,926 yuan a tonne at close.

But with Beijing still keeping a close eye on commodity prices and vowed to crack down on market irregularities, analysts warned of policy risks with steel prices hovering at high levels.

The August contract for stainless steel futures on the Shanghai bourse dipped 0.1% to 18,705 yuan a tonne.
