The women's crowns took the lead at the end of the first period.
Lisa Johansson broke a Finnish play and came into shooting position in the castle, but hit the post.
The return remained in front of the goal where Sara Hjalmarsson was the first to the puck and poked in 1-0.
Five minutes into the second period came the equalizer.
Seven minutes later, Finland took the lead and then scored five goals in less than five minutes of play to make it 6-1.
That after the Luleå players Viivi Vainikka, Petra Nieminen, Ronja Savolainen and Jenna Pirttijärvi scored goals.
In the third period, Jenni Hiirikoski, also in Luleå on weekdays, was able to score 7-1.
Sweden was able to clean up the numbers reasonably after 2-7 from Lova Blom's stick.
Noora Tulus, otherwise a great scorer in Luleå, accounted for two forward plays in the crush.
This was the Women's Crowns' third loss in four games this turn of the Euro Hockey Tour at home in Ängelholm.
One match remains, against the Czech Republic on Saturday afternoon.
